WebOct 25, 2014 · Continuing in this vein will give us the total number of inversions for array A once the loop is complete. Step 1 (merge sort) would take O (n * log n) to execute. Step 2 would execute n times and at each execution would perform a binary search that takes O (log n) to run for a total of O (n * log n). WebApr 15, 2024 · A simple approach would be to use two nested loops to count the number of global inversions and a single loop to count the number of local inversions. Algorithm: Set ‘GLOBALINV' = 0 and ‘LOCALINV' = 0. To count the global and local inversions. Run a loop where ‘i’ ranges from ‘0’ to ‘N - 2’:
